>I have a summary form, which loads various detail forms. On the summary form, I have some objects that I would like to pass to the detail form in order to not reproduce logic. I know I can save those objects as a class and handle that way, but I'm wondering if this is possible?

You can add custom property, pass object reference via init method and then store it to that custom property.
Then you can use/reference everything from that attached form.

*receiving form init
lparameters oSummaryForm  &&receive object reference
this.oSummaryForm=oSummaryForm  && Store it to custom property

*From here and on you can call/reference anything from that passed form anywhere in receiver form
SomeValue=thisform.oSummaryForm.SomeObject.SomeMethod()


**Before releasing form make sure you release reference of passed form as well
thisform.oSummaryForm=null
